For condensers not involving heat transfer, see Condenser (disambiguation). The condenser coil of a refrigerator In systems involving heat transfer, a condenser is a device or unit used to condense a substance from its gaseous to its liquid state, by cooling it. In so doing, the latent heat is given up by the substance, and will transfer to the condenser coolant. Condensers are typically heat exchangers which have various designs and come in many sizes ranging from rather small (hand-held) to very large industrial-scale units used in plant processes. For example, a refrigerator uses a condenser to get rid of heat extracted from the interior of the unit to the outside air. Condensers are used in air conditioning, industrial chemical processes such as distillation, steam power plants and other heat-exchange systems. Use of cooling water or surrounding air as the coolant is common in many condensers. Condenser unit for central air conditioning for a typical house In the world of Heating, Ventilation, and Air Conditioning (HVAC), condensers happen to be a topic of great importance.

Instead of confusing information, the goal is to provide some basic information on the different types of condensers and their applications. There are three other condensers used in HVAC systems Most common uses for this condenser are domestic refrigerators, upright freezers and in residential packaged air conditioning units. A great feature of the air cooled condenser is they are very easy to clean. Since dirt can cause serious issues with the condensers performance, it is highly recommended that these be kept clear of dirt.ac package units reviews They also require a cooling tower to conserve water. ac only unitTo prevent corrosion and the forming of algae, water cooled condensers require a constant supply of makeup water along with water treatment.what do air handling units do

Depending on the application you can choose from tube in tube, shell and coil or shell and tube condensers. All are essentially made to produce the same outcome, but each in a different way. Typically these are used in large commercial air-conditioning units. Although effective, they are not necessarily the most efficient. Prior to beginning your install, make sure you choose a condenser that will provide you with the most efficient use.→→ For an ideal single-pass condenser whose coolant has constant density, constant heat capacity, linear enthalpy over the temperature range, perfect cross-sectional heat transfer, and zero longitudinal heat transfer, and whose tubing has constant perimeter, constant thickness, and constant heat conductivity, and whose condensible fluid is perfectly mixed and at constant temperature, the coolant temperature varies along its tube according to:Written For the projects of our customers we use the following data for the design of the electrical installation:1.

- 3.5 ton AC, environmentally friendly R410A, split system, with both condenser and air handler, central air conditioner system.2. - It is equal to 42000 BTU of capacity.3. - Power supply of 208-230/1/60.4.- Rated current of 22.1 A.5. - 16 SEER Efficiency.At acquisition and installation time we verify the data from the manufacturer of the AC and we make the changes if any.Written This will depend on the weather! If it is especially hot outside the AC will have to work harder to cool your space. It is impossible to give you an accurate answer to the question, but sometimes estimates can be made based off of typical load profiles in your area.Benjamin LyddaneWritten This question is under-specified. The energy use depends on the time during which the compressor and fan are working, and on the efficiency of the device and on the temperature difference between inside and outside.The ton unit is a hold-over from the days when blocks of ice were delivered: in your case 3.5 tons a day. It is easy, but misleading, to work out the thermal energy stored in a block of ice when heated to room temperature ~ it is about 3.5 kW per ton of ice melted in a day.

(12000BTU/hr in American units) But it is rather strange to realize that air-conditioning is one of those rare devices that give out more thermal energy than the electrical energy they use. This ratio called COP can amount to an efficiency of 300% to 1000% though air conditioners are not usually rated like this, but in a peculiar mixed unit ratio called EER, Energy Efficiency Rating which mixes BTU (output) divided by watt.hours (input) as the efficiency measure.If units are converted to a uniform system, EER is like COP (Coefficient of performance) using a scaling factor in this way:(EER) BTU/hr /watts = (COP) Watts out / watts input all times 0.293Until recently, efficiency as EER as low as 6 was permitted. Now AirCon units must be at least EER 6 and better is 12.Let’s suppose your 3.5 ton unit is brand new and moderately high efficiency. That three and a half tons of ice represents 3.5 X 3.5kW thermal power divided by the efficiency multiplier now easily available (COP = 3.5) and we end up with 3.5kW as an estimate for the electrical power, consumed for as many hours as the outside temperature is too hot.

And that gets us to Seasonal SEER - but I won’t bug you with that.Updated I think it is 3.51KW per RT [refrigeration ton], although that does not account for inefficiencies.1 RT = 12000 BTU/hour.Refrigeration tons to kilowatts (kW) conversion calculatorwleWrittenHomeowners considering the option of a central air conditioning system should start by determining which type of system is best for their needs. Each system has its pros and cons, which are also important to take into consideration. There are two common types of central AC units: The split system is the most common option among homeowners. Most people are used to seeing this type in the backyards of homes. With split system units, most of the components are housed in a metal box on the outside of the home. However, there are some internal components as well. These can include the evaporator and heat pump. Split systems are ideal for cooling multiple rooms at once, but are not very energy efficient. Therefore, one pro homeowners can enjoy the benefit of not having loud equipment in their homes.

At the same time, the con would be that those who use this may spend more money on cooling costs in the long run because of the lower energy efficiency. A packaged unit, usually installed on the roof, is most commonly used on commercial buildings, but it is also an option for homeowners to consider. Often times, these units contain not only the air conditioning unit itself but also a furnace. A pro for this type of unit is great for those looking to save money on the installation of a new heating and cooling system separately, since the unit is combined. However, a con for these units are typically only available for larger homes due to their high power and capacity. Additionally, while they can be a good way to save money on a complete HVAC system, they are still significantly more expensive than buying just a cooling system. Therefore, this may not be the best option for homeowners looking for short-term savings or those with smaller budgets. It is important for homeowners to keep some specific considerations in mind before making a purchase.

For starters, it is a good idea to think about energy efficiency. By choosing a central AC unit that has as high of an efficiency rating as possible, homeowners can reduce their carbon footprint and save money in the long run. Often times, efficiency ratings are posted at appliance stores so that homeowners can compare their options. Going with an Energy Star rated appliance is a great way for homeowners to enjoy additional peace of mind. Aside from the unit's efficiency, there are some other factors that should also be considered before making a decision. Most homeowners do not realize the importance of an AC unit's size. A unit that is too large will have an easy time keeping the home cool, but will have a more difficult time removing humidity from the air. On the other hand, a unit that is too small will not be able to properly cool the home on hot days. Seeking help from a professional HVAC technician can help homeowners to find the size that is right for them. Many AC units come with a number of special features that can further improve performance and efficiency.

For example, homeowners may want to look for one that comes with a built-in filter light that will alert the user when the air filter needs to be changed. Another popular feature to look for is a fan-only switch, which homeowners can kick on at night to reduce energy costs even more. One of the greatest benefits of having a central AC unit installed is the lower noise levels compared to that of a window unit. As not all central units are made equally, homeowners should read reviews of various units to determine which ones have the best sound ratings, especially if the unit will be located close to a bedroom. There are many factors that can influence the overall cost of central air conditioning installation. One of the main factors is which components of the unit need to be installed. For example, a home with an existing central air system may already have the necessary duct work done and only a new outdoor central unit will need to be installed. On the other hand, if this will be the home's first time having a central air unit installed, then more ductwork may be required and the cost will therefore be higher.

Installation and material costs can have a great impact on the overall cost of the installation. For example, the units themselves typically cost around $2,000, but because of the level of work involved in installing and insulating a new unit, homeowners can expect to spend between $500 and $3,000 on labor and materials costs. However, it is always recommended that homeowners rely on a professional to install a new central AC unit, as this is not recommended as a do-it-yourself project. Homeowners feeling uncomfortable about the costs associated with central AC installation can benefit from shopping around to find the best deals. Comparing quotes among local HVAC companies can help to cut costs. Furthermore, requesting a quote during a non-peak time of year, the fall or winter, can also help homeowners to save money. In most regions of the country, HVAC companies are able to charge more during the months of spring and summer due to high demand. Before hiring anybody to install a central AC unit, it is always a good idea to read some online reviews of the company or contractor.
